Need basic MATLAB code upon Rate Splitting Multiple Access (RSMA)

Do anybody have basic MATLAB code upon Rate Splitting Multiple Access (RSMA), i.e. to get basic idea about the implementation of RSMA in MATLAB, Generation of common and private messages in MATLAB, etc...??

Did you find the solution, bro?

Prof Bruno Clerckx has provided some rate-splitting codes in his website, you can check those.

Sorry, I couldn't find the website you mentioned. Could you please provide me with a specific URL?"

Hi,

This is the basic Matlab code for the implementation of RSMA which I had tried. This might be helpful to you.

M = 4;  
N = 100;  
K = 2; 

s = randn(M, N); 
i = randn(M, N);  
n = randn(M, N);  
Ps = 1;  
Pi = 0.5;  
X = sqrt(Ps)*s + sqrt(Pi)*i + n;  

Rxx = (1/N) * (X * X');

[V, D] = eig(Rxx);

[~, indices] = sort(diag(D), 'descend');
Us = V(:, indices(1:M - K));
Ui = V(:, indices(M - K + 1:end));

w = (Us * Us' + Ui * Ui') \ Us;

y = w' * X;

Hope this helps!

Thank you for answering. But I think it is not correct as there are no specific common and private messages anywhere in the code.

If possible provide the MATLAB code to plot the Weighted sum rate (WSR) versus SNR comparisons of 1-layer Rate-Splitting (or any other RSMA scheme), NOMA, SDMA, Multicast schemes.
